Title: Improved manufacture of aromatic aldehydes
IPC: C07C45/36
Filed: 1922-10-23
Abstract: Aromatic aldehydes are produced by passing the vapour of an aromatic hydrocarbon containing substituent groups, one at least of which is an aliphatic group, in admixture with an oxygen-containing gas over a catalyst comprising an oxide of a metal of the fifth or sixth periodic group, other than vanadium. The catalysts may be prepared by depositing a suitable salt of the metal on a carrier, such as pumice or asbestos, and igniting the deposited salt to the oxide.  As oxygen-containing gas, air, pure oxygen, ozone or mixtures of these may be employed, with or without diluent gases or steam.  According to the examples, o-xylene yields o-toluic aldehyde over molybdenum oxide, a mixture of m- and p-xylenes give m and p-toluic aldehydes over uranium oxides, pseudo-cumene yields 1.2-dimethyl-4-benzaldehyde over tungsten oxide, mesitylene gives 1.3-dimethyl-5-benzaldehyde over uranium oxide, p-cymene yields p-toluic aldehyde over uranium oxide, and o-chlortoluene gives o-chlorbenzaldehyde over tantalum oxide.
